Tools for 3D Printing Enthusiasts
12 toolsTools for 3D printer owners, right in the browser. Preview a G-code toolpath layer by layer, work out print cost and filament length or weight, turn a photo into a lithophane or a 3D model, generate temperature towers, calibration cubes and Gridfinity bins, calculate stepper motor steps per millimeter, and identify a screw, thread or hex key by size.

Layer-by-layer toolpath, time and filament estimates
3D Print Cost Calculator
Filament + electricity + wear — drag in an STL or type the volume
Filament Length ↔ Weight Converter
20+ material presets — PLA, PETG, ABS, TPU, Nylon, carbon-filled and more
Lithophane Generator
Image → grayscale height map → STL — flat or curved
Temperature Tower Generator
Parametric STL + G-code with M104 per segment — any printer, any filament
Calibration Cube Generator
XYZ cube, retraction tower and flow tower — parametric, export STL
Gridfinity Bin & Baseplate Generator
Parametric bins and baseplates — export STL for any 3D printer
Photo to 3D Model Scanner
AI depth or turntable silhouettes — export STL, slice and print
Stepper Motor Calculator
Configure stepper motor steps/mm for 3D printers, CNC machines, and robotics firmware.
Thread Gauge
Measure ten threads on a calibrated screen to get the pitch, TPI and matching sizes. The 1:1 printable sheet adds pitch combs, radius arcs and a feeler table.
Screw Gauge
Measure a screw on your calibrated screen, or print a true-to-size paper gauge — then read its diameter, thread pitch and length.
Hex Key Gauge
Measure a hex key on your calibrated screen, or print a true-to-size gauge — then read its metric or SAE size.
